Title: Allotropic modifications of carbon@ other than graphite and diamond - are formed by dissolving carbon@ in a metal or salt and then reducing the solvent content under controlled conditions
IPC: C01B31/02
Filed: 1991-03-16
Abstract: Allotropic C modifications, apart from graphite and diamond, are formed by dissolving C in melts of metals, including alkali- and alkaline earth-elements, and/or salts and subsequently reducing the solvent content. The dissolution is pref. carried out at a temp. between m.pt. and critical temp. of the solvent, pref. under a, pref. controlled, pressure at least equal to the solvent vapour pressure. The pptn. of C can also be carried out by cooling down to a temp. above or below the m.pt., pref. at a controlled rate. Solvent may also be extracted, pref. at a controlled rate, at the same time as the cooling takes place. Foreign atoms can be built into the C matrix by adding them to the melt as elements or cpds. e.g. by contacting the melt with a liquid or gaseous coolant which contains the elements or ions required. An electrical bias can be applied between the solvent and the coolant. Also claimed is the process of building foreign atoms into a C matrix by contacting the matrix with the elements or ions under the correct thermodynamic conditions. USE/ADVANTAGE - Gives alternative C-allotropic modifications in a controlled way, i.e. dependent on controlled formation conditions. The process yield is high compared with current processes involving deposition from the gas-phase. The content of graphite e.g. can be influenced by the speed of evaporation of the solvent. The use of an electrical bias can concentrate the particles formed in a required area (electrostatic particle pptn.)
Patent DE-4109812-A1 (DE)
Title: Protection of non-aq. lithium cells against over-discharge - by the use of conductive organic polymers which can be reversibly charged and discharged and alter their conductivity
Inventor: NAARMANN HERBERT DR
IPC: H01M4/62
Filed: 1991-03-26
Abstract: Electrochemical sec. batteries using non-aq. electrolyte, based on Li, have a positive electrode contg. a reducible inorganic material. The batteries have between the active material of the anode and its current connection, a contact medium made of a polymeric material. The polymer can reversibly gain and lose ionic dopant and so be charged and discharged which results in a variation of conductivity. The polymer can be used to form a matrix in which the active material is embedded or be mixed with the active material in powder form, pref. giving a ratio of polymer to active mass of 1-30 wt.%, esp. 5-15 wt.%. The polymer can also be used in the form of a film, pref. 0.1-100 micron, esp. 2-20 micron thick, between the current connection, which is pref. metallic, and the active mass or as the current conductor. USE/ADVANTAGE - The construction prevents discharge below 2V because of the increase of the resistivity of the polymer material. The cell can still be discharged to below 2 V, but this has no effect on the active mass, which is shielded by the polymer. The method is used in Li-cells to give a higher resistance against over-discharging esp. in low drain cells. In an example, a button cell with Li metal cathode and MnOx active mass, mixed with soot, at the anode was made with conventional construction (1) and another cell was made using an addition of powdery polypyrrole to the MnOx. The electrolyte used was 1M LiClO4 in propylenecarbonate. The fig. shows the effect of several discharges, including over-discharges on the cell capacity.
